Date Mon, 10 Oct 2011 07:20:29 GMT
Circular reference in Deserialization and XMLReader
---------------------------------------------------

                 Key: AXIS-2862
                 URL: https://issues.apache.org/jira/browse/AXIS-2862
             Project: Axis
          Issue Type: Bug
          Components: Serialization/Deserialization
            Reporter: Nagaraj
            Priority: Critical


I got out of memory error and when i analysed heap dump, i was getting infinite active references
of deserialization and xmlreader.When expand Deserialization context,XMLReader reference is
there and when expand XMLReader,Deserialization reference is there.It seems to be circular
reference.The sample output of heap dump is given below.                                 
                                                                                         
  
                                                                                         
                                                                                   | Shallow
